Application filed August 11, 1909. Serial No. 512,413.

To all whom it may concern:

Be it known that I, LYMAN R. Swnr'r, citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have inventedv certain new and useful Improvements in Envelops, of which t-hefollowingis a specification.

My invention relates to envelops having a plurality of receptacles, or pockets, and is specially adapted for church collection purposes.

The accompanying drawing illustrates the device, iIt-w'hich- Figure 1 shows a blank of which the envelop is made; the parts coated with the adhesive being in shaded lines. Fig. 2 shows the back of the completed envelop, ready for use, and Fig. 8 is a view of the back of the envelop closed and sealed.

The letter a designates the'quadrangular body of t-heenvelop blank. I), b are side flaps thereon, whose upper edges 0, 0, are nearly in line with the upper edge 1, of the. completed envelop. I

c is the lower flap preferably made quite broad at its outer edge f and adapted to be folded'over and pasted upon the flaps b, b.

y indicates the central, gummed part of the body a, which adheres to the centralpart of the lower flap 6 when the latter is folded upon the body, and so divides the interior of the envelop into two compartments or pockets. closed upon all. sides except the upper side. The envelop is finally sealed by moisteniug the dry gummed portion h, of the upper fiapfiz', and folding it down upon the flaps b, b and ex The envelop is printed, preferably While in the blank form, to indicate the purposes to which the contributions are to be applied. In order to separate the pockets from each other, so as to pass each one to "the officer having the care of the differentcollections, I indent or perforate the envelop along a central line le,'extending from the lower edge 7', of the envelop'to the lower limit (l of the top flap 2', or at farthest to the drygummed portion h of flap 2'; thus employing all, or nearly all of the breadth of the top flap 'i, when pasted down, to strengthen the perforated line 7c, against its great liability to be torn apart in handling.

The general form of the blank shown is triangular and is characterized by requiring the ininimumof stock used, and the very small quantity of waste resulting.

I employ a single closing flap '2', in preference to two flaps, for sealing the two pockets, as it is easier to 'guin one fiap than two, and in sealing it is easier to moisten one flap than two, thus saving time and trouble; besides which, as already stated my single flap reinforces a weak part of the structure; \V hat I claim and desire to secure, is-

An envelop formed from a blank having a quadrangular body, approximately rightangled side flaps whose upper edges are nearly'in alinenient with the upper edge of the sealed envelop, a bottom flap having a broad outer edge, a central adhesive surface on said body adapted to adhere'to the folded lower flap, there being a line of central cross perforations short of the width of the envelop, and a single dry-gummed sealing flap adapted to seal both pockets-as described.

In testimony whereof I affix my signature, in presence of two witnesses.
